Chest space - the final frontier
• These are the voyages of the starship Ultrasound
• Its continuing mission:
– to explore strange new pictures
– to seek out life
– and new meanings
• To boldly go where only horse
has gone before

3.
Normal lung - no lung image
just artifacts
just artifacts
• Soft tissue/air interface 99% of ultrasound waves is reflected
• Lung is full of air if normal so ultrasound cannot be used to
image healthy lung, only the pleura
• But...
– with disease process lung loosing aeration
– less US beam reflection and more penetration

• Absence of lung sliding
• Absence of any B-line
• Potential presence of a lung point
